1x7 - Punch Line

Yūta returns to his own body on December 21, right after the busjacking incident. After reviewing the upcoming important dates, Yūta is informed by Chiranosuke that he must change the future, which his previous selves failed to do, without revealing the truth to anyone or changing the future without his permission, further explaining how his nosebleeds results in mankind's destruction. After setting up talismans to keep his spirit double from reaching his body, Yūta decides against writing "U-Turn" into the Nandala-Gandala, feeling it would be admitting defeat, while also managing to prevent his spirit double from seeing the girls' panties. The next day, as Yūta tries to ask Rabura about Gliese, he spots Tomoda and pursues him, but is stopped by Chiranosuke, who tells him not to undo the events that helped the residents form bonds with each other. Chiranosuke further explains that the reason Yūta's soul so easily detached from his body is related to an event nine years ago. During this event, Pine, Chiyoko, and Guriko ended up switching bodies with each other during an escape attempt when a lighting strike hit their Über-fied states, with Yūta being the result of Pine's soul winding up in Chiyoko's body. Back in the present, Yūta receives a package from his foster sister, Akina Iridatsu, which turns out to be the Kenji Miyazawa costume.
